END WALL noia RAILWAY cARs.

Application led March 8, 1926.

lwiy invention relates to the construction of a railway car having an end wall made of one or more metallic plates secured together and reinforced with stiffening and bracing members. Thilo efforts are made to block the lading in the car, the shocks caused by the heavy locomotives, the emergency air brake and the classification hump tear the lading away from its moorings and throw it against the end of the car, and the lateral weaving of the car throws it against the side of the car. The invention is readily adaptable to box, gondola and other types of railway cars.

One of the objects of theinvention'is to provide a wall element which has great strength to resist the torsional and weaving stresses which exist in a railway car when moving in service. These stresses are caused by the inertia of the roof and superstructure when the train is suddenly stopped; rough or uneven track; the superelevation of the track on curves; the lateral inertia. in rounding curves; eccentric thrust due to the lading being secured to one side of the car; the cars being cornered; the use of push pole pockets, etc. Such stresses rack and distort thc superstructure which decrease the life of the car, and also causes the car to leak grain, sand, and other such material. Furthermore, such stresses cause leaky roofs and leaky and inoperative side and end doors.

An object of the invention is to provide means to reinforce metallic plates forming the end wall of a railway car and to secure a lining to such reinforcements so as to provide a weather-proof construction.

Another object is to provide a composite end wall for a railway car, the steel parts of which are simple to manufacture, especially as they require no heating for forming.

Another object of the invention is to provide a metallic end wall for a railway car which is stronger adjacent the floor of the car, where experience has shown greater strength is required.

Another object is to attach a woodenlining to a metallic end wall by means which do not penetrate the metallic wall.

In the drawings:

Fig. l shows an end elevation of a railway car with my device applied thereon.

Fig. 2 is a section on line 2-2 of Fig. l.

Fig. 3 is a section on line 3-3 of Fig. l.

Fig. 4 is a section on line 4-4 of Fig. 1.

Serial No. 93,265.

Fig. 5 shows a modified form wherein the railway car has an angle bar corner post.

The end wall comprises one or more me tallic plates 2 secured together to form a panel, which panel is secured to the adjacent frame members of the car, such as the end sill 3; end plate-4L: corner post 5 (or corner post 6. as shown in Fig. 5).

The plurality of plates may be secured along vertical lines or horizontal lines, as desired.

The metallic plates are strengthened by reinforcing bars 7 which are riveted, wel-ded or otherwise secured to the inside of the metallic plate 2 in such a way as to provide a weatherproof construction. These reinforcing bars may extend parallel or normal to the meeting edges of the plates but in the drawings they are shown parallel thereto. These reinforcing bars are positioned closer together adjacent the fioor of the car so as to make that part of the end wall stronger than elsewhere. The lining 8, which is preferably of wood, is secured to the reinforcing bars independently of the plate. This is preferably accomplished by providing nailing strips 9 which are bolted to the reinforcing bars as illustrated.

The preferred form is shown in Fig. 4 where the reinforcing bar comprises two arms, one of which (-10) is riveted to the plate and the other of which (ll) provides means for attaching` the lining through the medium of a nailing strip or otherwise.

If the railway car is provided with an angle iron cornerfpost (6) the plate may simply be riveted to one leg thereof, thereby dispensing with the flange, all as shown in Fig. 5.

In my construction I use fiat plates requiring no heating process to form them. The fianges l2, shown in Fig. 3, can be formed cold. The reinforcing bars are made of standard structural shapes cut to the desired length, thus eliminating any expensive forming process. The several plates and the reinforcing bars can be secured together before the end wall is applied to the car end, and if desired, the nailing strips and lining could also be assembled with the end wall before it is applied to the car.

I claim:

l. An end wall for a railway car comprising a metallic plate attached to the opposite frame members of the car, a reinforcing bar Comprising two arms, one of which is SeV cured to Suid plate so as to provide a weatheif-proof Construction, a nailing strip secured lo the odiei' of said arms, and a lining secured to said nailing strip independently of said plate.

2. A n end Wall for a railway car comprising ametallic plate attached to the opposite frame members of the cui, 'a plurality of reinforcing; bars Secured to Said plateV so as to piovide a Weather-plooi: Construction, said bers positioned closer ogether adjacent the floor of the ozu', and a lining secured to said bars independently of said plate.
